44075aa0f0 sw_engine: Improved the blur performance by 12% 
Applied the compromised approach for the gaussian blur
since the effect is a bit burdensome for cpu processing
as animatable effects.

- Optimized performance and quality with negligible observable differences.
- Disabled the border option until specific use cases are identified.

df0658e2da renderer: improved engine for scalable effects 
RenderMethod effects methods would have changes:

sw_engine: Fix buffer overflow in texture mapping rasterizer 
Fix heap buffer overflow in texture mapping rasterizer by adding proper
bounds checking for texture coordinates. This prevents accessing memory
outside of the allocated image buffer during texture sampling and
interpolation.

096b834771 lottie: fix text stroke's 'of' property 
The text stroke's 'of' property determines whether
the stroke appears above (true) or below (false)
the fill.
Previously, it was incorrectly used to decide whether
the stroke would render.

38a4465656 lottie: fix viewport clipping issue when resize 
After resizing an animation, the base clipper for the viewport of the root scene did not update accordingly. This caused the animation to always be clipped by its initial size.

Additionally, this issue introduced a regression in v1 when the `Result Picture::size(float w, float h)` function was called.
